New to me 2006 Fleetwood Wilderness

I am thinking it wouldn't be worth it to upgrade the wheels, I just want the peace of mind that getting new tires a bit overrated will give for my cross country move that I will be making in the next few months.

I searched for tires with the stock size, really only two options, but will probably go with Load range E Goodyear Endurance tires.

I still have research to do when it comes to the hitch, but I like the design of the Reese setup.
